Errors after battery disconnect

[DusHunter]

Hi friends,

yesterday i disconnected the battery from the electrical system for a couple of seconds.
After reconnect the battery I received many erros in the front display (ESC+ABS Airbag, Diff locks).
Do you know how what to do?

Disconnect it again. Then discharge any capacitors in the electronics by switching on something that is always live (brake pedal, horn etc).
Then reconnect.
The airbag light might stay on, but it will go with a bit of driving.

to reset or do what is called a hard reset disconnect the battery terminals and leave them disconnected for at least 10 minutes
You can also touch the cable terminals together for a few minutes ( do not connect battery terminals together just the cables when disconnected from the battery)
This will drain all voltage from the electronics in the car.
This is a Discovery 3 and 4 method of doing a hard reset
I am not familiar with the duel battery system in the IG so it would be advisable to disconnect both batteries, main starter first then the secondary battery would be the logical choice but a check of the owners manual may help as well
